We relate to thee their story in truth: they were youths who believed in their Lord, and We advanced them in guidance: 13 And We made firm their hearts when they stood forth and said: Our Lord is the Lord of the heavens and the earth. We cry unto no Allah beside Him, for then should we utter an enormity. 14 These people of ours have taken deities other than Him. Why do they not produce clear evidence about them? Who is more wicked than the man who invents a falsehood against God? 15 So, when you have gone apart from them and that they serve, excepting God, take refuge in the Cave, and your Lord will unfold to you of His mercy, and will furnish -- you with a gentle issue of your affair.' 16 ۞ And [had you been present], you would see the sun when it rose, inclining away from their cave on the right, and when it set, passing away from them on the left, while they were [laying] within an open space thereof. That was from the signs of Allah. He whom Allah guides is the [rightly] guided, but he whom He leaves astray - never will you find for him a protecting guide. 17
